“Removal of environmentally harmful NO2 and SO2 from various gas streams is important for the protection of human health and the environment, for CO2 capture and sequestration (CCS) and for energy-efficient fuel cell applications. Although there are commercial technologies such as flue gas desulphurization (FGD) for SO2 removal and selective catalytic reduction (SCR) for NO2 removal, alternative and more environmentally benign methods based on solid sorbents with better energy efficiency and easier handling are highly desirable. The present work aims at a new approach based on a polymer-based solid sorbent for removing toxic NO2 and SO2 at room temperature under atmospheric pressure without using catalyst and without involving chemical reactions. We have developed a novel type of nano-porous molecular basket sorbent (MBS) based on polyethylene glycol (PEG)-loaded mesoporous molecular sieve SBA-15 for removing more than 99% of NO2 and SO2 from gas streams at room temperature and atmospheric pressure. The spent sorbent can be regenerated easily and completely by heating to 100 °C. With this new approach, the present study may open a new window for developing environmentally-friendly high-performance solid sorbents for SO2 and NO2 removal from various gas streams.
